Using a (first) piece of your blank scratch paper, determine the area of the triangle below.  

(a) How much heat transfer is necessary to raise the temperature of a 0.200-kg piece of ice from −20.0ºC to 130ºC, including the energy needed for phase changes? (b) How much time is required for each stage, assuming a constant 20.0 kJ/s rate of heat transfer? (c) Make a graph of temperature versus time for this process. Note: Ice’s specific heat is 2090 J/(kg⋅ºC) and latent heat for water at 0ºC is 334kJ/kg.

The engine of a large ship does 2.00×108 J of work with an efficiency of 5.00%. (a) How much heat transfer occurs to the environment? (b) How many barrels of fuel are consumed, if each barrel produces 6.00×109 J of heat transfer when burned?

If net income after taxes are $60,000 and owners’ equity is $200,000, how much is return on owner’s equity (as a percentage)?

If net income after taxes is $50,000 and owners’ equity is $400,000, how much is return on owner’s equity (as a percentage)?
